Title: Numerical Experiment on the Hubbard model
Abstract: The Hubbard model is one of the fundamental models of correlated electron physics. In two dimensions it exhibits superconducting, Mott insulating, magnetically ordered, pseudogapped, and metallic phases. On a square lattice and for repulsive interactions comparable to the bandwidth, the model is believed to capture much of the low-energy physics of the cuprate high-temperature superconductors, while in three dimensions it can be realized experimentally in ultracold atomic gases.
In this talk I will show results from `numerical experiment’ on this model and compare them to experimentally obtained response functions and theoretical calculations, illustrating how simulations can be used to further our understanding of correlated electron systems.
